To all wfiom it may 'cbncern: Be it known that we, ALBERT A. MAGLEOD andLoUIsM. BROW citizens of the' United States; residing at 'Swam'pscottand Beverly;

In'the manufactureof a welt shoe the up per is lasted against {theupstanding lip or rib ofthe innersole at the sides and toe of the shoeand secured temporarily in place by tacks. At the heel theup'per islasted down upon the heel seat and secured permanently by'tacks.Theupper is then sewed,

together with the'welt, to the lip or rib of the innersole from} thebreast edge of the heel seataround' the-periphery of the fore p'a'rtofthe, shoe and back to the breast edge of the heel seat. Theupper, weltand innersole connecting'seam is called the inseam and thissewing'operati'on is performed by a special sewing machine called awelter. In making some yarieties of Welt shoes the welt strip, instead ofbe severed at the heel breast line at the completion of the weltingoperation,

subsequently secured around the heel seat of the "shoe, either toprovide' a continuation of the welt to! whichthe outsole be attached orto provide a rand between the heel seat and the lifts of the heel.Sincethe up-v per of the shoe has already beenpermanenfly secured to theheel seat by the lasting tacks,-

and innersoles are not usuallyprovided with lips around the heel seat,the; operation of attaching the extension of the-welt'to the heel seatcannot beperformed by the'welter.

It is the general object of this invention as" provide "a machine whichwill be well adapted for performing the operationof'atis allowed toextendfrom thein seam a ufficient amountso that it may be titlching awelt to the heel seat of a lasted s oe.

The'marg'in of the heel seat'face ofa lasted shoe presents an unevensurface be} cause of the lastingv tacks and folds of the upper; Oneimportant feature ofathis in vention consists in meansftefacilitatethemovement of the shoe progressively under the work rest of the weltattaching machine as the attaching operationproceeds. This means maycomprise; as shown; a member which engages the heel seat over aconsiderable'a'rea adjacent to" the line along which the welt is to beattached and which has a'smooth surface'in contact with which thesurface of the heel seat may readily slide. In the illustratedembodiment of this invention this means comprises a plate which isadapted to be inserted between the welt andthe heel seatand is locatedimmediatelyin advance of the lineof action'of Y the welt attachingmeans, said plate being preferably connectedunovxbly to suitablesupporting" means. The plate may, as here'- in shown, have a normallydepressed position to facilitate the insertion over it of the welt stripprojecting 'rearwardly from the inseam, as above" suggested, and theplate may be constructed and arranged to, be moved upwardly toworking'position by the shoe asan incident to the operation ofpositioning'the shoe in. the proper relation to theweltattachingmechanism; I

Another feature of theinvention consists in a' welt inclosing guide, ofwhich theheel seat engaging plate above mentioned, .preferably forms alower wall. As shown in the drawings, the welt-attaching: means is, atacker provided with a .rigid work' rest against which the shoe may bepressedfup wardly to receive tacks. In the lower face. of this rest isformedza recess across which. the said engaging plate extends a) confinethe welt. An inclosing'guide. for the welt is. important becauseresistance ofthewelt to being bent edgewise around the curved p01?tion.of the heelis likely to cause the iweltto escape. from the weltguide unless thewelt is substantially surrounded. -Iffthe heel seatengaging plate formsithe lower, wall pr the guide and has a normallydepressed. position, the welt guide is normally'open and the welt isreadily positioned in the guide by a movement of the shoe laterally ofthe welt strip; that is, by a substantially horizontal movement of theshoe into position beneath the tacker. This arrangement enables a weltstrip having one end secured to the shoe to'be introduced. into the weltguide by the usual and necessary movements ofthe shoe into operativerelation to the securing mechanism, and therefore without especialattention from the operator, and saves the loss of time which would berequired to thread the welt end through a permanently closed guide.

These and other features of the invention will appear more fully fromthe following description when read in connection .with the accompanyingdrawing and will be pointed out in the appended claims.

In the .drawing, v

Figure 1 is a perspective view of an embodiment of my invention;

Fig. 2 is a plan view of the welt guide and edge gage showing a shoe inposition for the operation of attaching an extension of the welt aboutthe heel seat thereof; I

Fig. 3 is a side view of the parts shown in Fig. 2, including asectional view of the top portion of the jack post; and

Fig. 41 illustrates the appearance of the shoe after the completion ofthe operation of securing the welt end about the heel seat.

Referring to Fig. 1 of the drawings, the reference character 2 indicatesthe frame of themachine. A driver 4 is mounted to be reciprocated at aslight inclination to the vertical and cooperates with a tack block 6which reciprocates horizontally from a rearward position in which itreceives tacks which are automatically fed to it from a raceway to aposition under the driver which passes through the block and forces thetack int'crthe work. A support 8 issecured to the machine frame 2, asshown in Fig. 8, and to thesupport 8 is adjustably fastened by screwsand slots at 10 a rest or abutment 12 which is provided with a notch 14;over which the tack block 6 lies when in its forward position andthrough which the driver operates to insert a tack into the work. Byloosening the screws 10, the rest 12 may be adjusted to bring the notch14: into alinement with the driver. On the under face of the rest 12 andlaterally in a line with the notch 14 is a recess or groove 16 whichforms a guide for the welt which is to be secured to the work. At theback of the recess 16 is a member 18 which is arranged for adjustment tovary the size of the groove to adapt it to different widths of welting.The members-18 is T-shaped, as shown in Fig. 2, and is held'in adjustedposition by a screw and slot adjusting means 19. To the under face ofthe rest 12 is secured, as by rivets 20, a plate 22 to the forward endof which is movably secured, as by a hinge, at 24 a plate 26 whichunderlies the groove 16 and preferably conforms to the contour in planof the forward portion of the rest 12. The right-hand or advance edge ofthe plate 26 may be upturned, as shown inFig. 3, to facilitate thepassage of the work thereunder.

An edge gage 30 is provided which preferably is a steeply inclined,frusto-conical fiber roll, the upper and larger periphery of whichcontacts with the side of the shoe at a point in very close proximity tothe plane of the shoe bottom where the shape of the shoe is such thatthe edge gage will insure the securing of the welt at a uniform distancefrom the edge of the last bottom. A handle 32 is provided which may begrasped by the operator by the same hand which holds the shoe inposition against the rest 30, and this handle may conveniently be formedas an extension of the pivot upon which the roll 30 is mounted.

The jack for supporting and positioning the shoe relativelyto the weltguiding and attaching means is in most respects similar to that shown inUnited States Letters Patent No. 919,4:24, granted April 27, 1909, onapplication of William H. Gulf, and reference may be had to thatpatentfor details of the mechanism not herein given.

The center about which thejack post swings in its to and fro movementsto carry the shoe into and out of position to be operated upon should bein vertical alinement with the driver in order to firmly support theshoe and to effect this a toothed segment 42 which engages a rack 40 isformed on a yoke member 46 havingrearwardly projecta ing arms to whichare'pivoted at 4:8 arms of 5 1 against the action of a spring 58, andthe jack post may be quickly adjusted vertically to accommodatedifferent heights of last and to quickly adjustthe force with which theshoe will be upheld against the rest 12 by operating a handle 62 to varythe relation of the cam faces 64, 66. By means of the yokes 4:6, 50, itwill be apparent that the pivot about which the jack post is'swung iscarried rearwardly to a point which is substantially in verticalalinement with the driver and with the heel pin upon which the shoe isspindled when'the shoe is" in position to be operated upon. The jack isprevented from swinging about the supporting post 7 0 by a block 72mounted on one of the supporting brackets of the jack and engaging agroove 7 1 formedin the jack frame as shown in Fig. 1. I

To prevent'thefcatchingiof the upper between thecrown of the 'last'andthe flange at the base of the heel pin, the construction shown in Figs.1 and?) is providedwliich comprises a collarSO which slips easily uponthe last pin 82 and in the periphery of which are pivoted a series oftoggles or jointed members 84, the opposite ends of which are similarlypivoted in a'fiangeformeclf on the mid portion of the pin 82 w'hichisseated in theusual manner in the top of the jack post.

The toggles are normally held'in a partially straightened position, asshown in Fig.1, means of a spring 86 acting on a pin 88 which passesthrough the collar and rides in a vertical slot 90. in the last pin 82.The hole in which the spring 86 is seated is extended upwardly as far asthe slot 90 to permit the spring to act upon the pin 88 and to hold thetoggle members in the position shown in Fig. 1. WVhen the shoe ispresented to the last pin 82, the action of the toggle members as theyare bent by pressure of the crown of the last upon the collar 80 is topush the upper away from the last and heel pin so that it cannot bepinched between the crown of the last and the collar 80 and injured whenthe last is forcibly upheld against the rest by the jack.

The mechanism described in the above paragraph is not claimed herein butis made the subject-matter of a divisional application Serial No.231,514, filed April 29, 1918.
